OPTIMIZATION OF “TIG WELDING”: A STUDY

Objective: In this review paper author discusses about the enhancement of TIG welding. Tungsten Inert Gas (TIG) welding will be welding procedure of uniting diverse materials with top notch weld dab by electric curve age between non consumable terminal and work piece under a protecting gas. It is utilized to weld ferrous and non-ferrous metals. It is otherwise called Gas Tungsten Arc Welding (GTAW) process. This procedure infer a few focal points like low warmth affected zone, joining of not at all like metals, nonappearance of slag, high warmth focus and so forth contrasted with other welding process. The TIG welding parameters are the most essential components influencing the quality, profitability and cost of welding. TIG Welding execution is for the most part assessed dependent on Tensile Strength of the weld, Weld dot Geometry, Hardness, Depth of Penetration and Depth proportion Also known as Aspect proportion. In the present investigation, we examine the impact of the distinctive welding parameters, for example, welding speed, control source, kind of current, protecting gas stream rate, cathodes, filer wire, Electrode hole and sorts of protecting gases which fits best to decide curve steadiness, circular segment entrance and deformity free welds.
